Andrea has 1 hour to spend training for an upcoming race. She completes her training by running full speed the distance of the race and walking back the same distance to cool down. If she runs at a speed of 9mph and walks back at a speed of 3mph, how long should she plan to spend walking back?

Answers

Answer 1

Answer:

  3/4 hour

Step-by-step explanation:

The ratio of speeds going : coming is 9 : 3 = 3 : 1. The ratio of times will be the inverse of this: 1 : 3.

The time spent walking back is 3/(1+3) = 3/4 of the total, or 3/4 hour.

Andrea should plan on walking back for 3/4 hour.

Answers

The amount that will be spent is $24.50, the amount saved will be $10.50, and the percentage saved will be 30%.

The amount that will be spent will be:

= 7/10 × $35 = $24.50

The amount that will be saved will be:

= $35 - $24.50 = $10.50

The fraction of the original price that is saved will be:

7 √(1/3) - 2 1/3 √(1/3) +3√147

→7(1/√3) - (7/3)(1/√3) +3√(3×7×7)

→ (7/√3) - (7/3√3) +3×7√3

→ (7/√3) - (7/3√3) + 21√3

On Rationalising the denominators then

→ [ 7√3/(√3×√3)]-[7√3/(3×√3×√3) +21√3

The Rationalising factor of√3 =√3

→ (7√3/3)-[7√3/(3×3)]+21√3

→ (7√3/3)-(7√3/9)+21√3

LCM of 3 and 9 = 9

→ [(3×7√3)-(7√3)+(9×21√3)]/9

What are the solutions to the quadratic function. f(x) = x^2+4x-12

Answers

Answer:

2, -6

Step-by-step explanation:

x^2 + 4x - 12

A = 1

B = 4

C = -12

i used the "X" method to solve for the solutions. i think it's easier than using the quadratic formula but it doesn't always work

for the "X" method you have to multiply your A value and your C value together so 1 x (-12) = -12. that is going to be the top part of the X

the bottom part of the x will be your B value which is 4

we have to find multiples of -12 that will also add to 4

so -2 and 6 multiply to -12 but also add to 4 so we know these numbers will work

A Chevrolet Sonic Hatchback costs $14,845.00. With a 15% down payment, you can have an amortized loan for 6 years at a rate of 4.5%.

A) What will the monthly payment be?

B) How much will the car cost, in total?

C) How much money will be paid in interest?

Answers

Using simple interest, it is found that:

a) The monthly payment will be of $222.57.

b) In total, the car will cost $18,251.9275.

c) $16,025.1775 will be paid in interest.

The amount of money accrued after t years, using simple interest, with an initial value of P and a decimal rate of r is given by:

[tex]A(t) = P(1 + rt)[/tex]

In this problem:

Total cost of $14,845.00, with a down payment of 15%, hence the initial value that will accrue interest is [tex]P = 0.85(14845) = 12618.25[/tex].Loan for 6 years, hence [tex]t = 6[/tex]Rate of 4.5%, hence [tex]r = 0.045[/tex].

Item a:

The amount of money accrued will be of:

[tex]A(6) = 12618.25[1 + 0.045(6)] = 16025.1775 [/tex]

Payment over 6 x 12 = 72 months, hence, the monthly payment will be of:

[tex]m = \frac{16025.1775}{72} = 222.57[/tex]

The monthly payment will be of $222.57.

Item b:

The total cost is composed by:

Down payment of 15%, out of the amount of $14,845.00.Interest of $16,025.1775.

Hence:

[tex]T = 0.15(14845) + 16025.1775 = 18251.9275[tex]

In total, the car will cost $18,251.9275.

Item c:

As found in item a, $16,025.1775 will be paid in interest.

AGAIN BE SERIOUS THIS IS DUE TOMORROW Over the past ten years more than two dozen athletes have died from the medical condition known as heatstroke. Heatstroke occurs when the body's internal temperature becomes soelevated that its cooling system begins shutting down. Who is most at risk? Surprisingly, it is younger athletes. They often either do not recognize or ignore the warning signs until it's toolate. To make matters worse, children's bodies are much less efficient than adults at cooling themselves. A promising new product hopes to end the all too common heatstroke trend. It iscalled a thermometer pill2 While it doesn't look much different from the average vitamin capsule, the work it does inside the body is truly amazing. Once ingested these capsules send an internal bodytemperature reading to a portable device that is not much bigger than an iPhone. A coach or professional trainer monitors the device during practices or events held when temperaturesand heat indexes are particularly high. If an athlete's body temperature reaches a dangerous level, the monitor immediately transmits an alert. The player is then rushed indoors andplaced in an ice bath to rapidly decrease his or her body temperature. This is important, since internal organs can begin shutting down at 105 degrees Fahrenheit5 While these tiny lifesavers have proven to be effective, they are quite expensive. On average the cost is $50.00 per pill. However, many parents of young athletes say that it is a smallprice to pay for the piece of mind it gives them on a hot, sultry day.1) Which of these BEST describes the author's view about thermometer pills?A) The author thinks thermometer pills are effective but too expensive.B) The author thinks thermometer pills need more testing to be considered safe.The author thinks thermometer pills are a potentially promising answer to heatstroke.D) The author thinks thermometer pills are the only way to protect young athletes from heatstroke.
